I am not sure if this is a new topic. I have been able to get the 3ds max exporter working and have been using it off and on. The AutoCAD exporter however does not seem to work. It installs and I can go through the motions to export a model but a message comes back saying "Failed to upload the model to SketchFAB.com. I've tried uninstalling and then installing from the exchange store. No luck. Then I tried the other technique which is to export the SktchFAB bundle to the AutoCAD plugins folder. Still no luck.
Does anyone have any insight into this problem? When the feature is uninstalled through the control panel, does this remove it completely? Or is there something else I need to do to start over?
